ETL 505: Module 2; Information Retrieval tools.

Posted by arlekeno on July 13, 2012

Tools used in libraries for retrieving information include:

Library catalogues

Classification schemes such as the Dewey Decimal Classification, the Library of Congress Classification and the Universal Decimal Classification: these group together information on the same or related subjects

OOh, LIbrary catalogues are over 4500 years old. Not too shabby. Lets hope they survive the internet 😛

I really need to get a grip on the concept of PROVENANCE.

I am looking at the documentation movement, (pg 63), and remember my radings from yesterday where we thought we could just digitise everything due to teh low cost of data storage. I wonder how long it will take for use to run out of hard drive space, the way Libraries last century had to resort to Micro-film.

ASSOCIATIVE INDEXING… I like this idea. Its how we think subjects link.pg (64) Vannevar Bush, HE THE MAN!

“Information Science is Library Science for men” Love it!

A bibliographic record in a library catalogue has two parts:

a description consisting of the physical attributes of the information carrier (such as number of pages, title, size) and of details about the resource’s creation, publication, etc. (for example, author);

a description of what the document is about (its subject), consisting of words selected from a standard list of authorised terms (for instance, a thesaurusor a subject headings list), a classification number, and sometimes a brief description of what the document is about (an abstract).

(am meant to read Chapter 14 of our text now but it still has not arrived!)
